Definitions
- Rotary disk filters are known from, for example, SE-C-224,131.
- water is conducted through one end of a central rotatable drum and through openings in the circumference of the drum radially outwards to disk-shaped filter chambers.
- Each of the filter chambers is defined by a disk-shaped filter member having opposing filter portions which are supported by an annular filter support arranged between the same.
- the filter members are mounted in parallel along the longitudinal axis of the drum. When water flows out through the filter portions, particles are retained in the filter chambers.
- the filter support between the filter segments advantageously comprises a framework construction, whose hollow spaces constitute the second liquid ducts. In this manner, liquid communication can easily be provided, while at the same time the support can be made sufficiently strong with great economy in material.
- the filter support is preferably made of plastic and can thus be manufactured at a relatively low cost. Further the filter support will be corrosion-resistant.
- the rotary disk filter 1 is provided with flushing nozzles 7 for cleaning of the filter cloth 4, which are mounted on a number of flush tubes 8 which extend between the disk-shaped filter members.
- the flush tubes 8 are adapted to conduct flush liquid to the flushing nozzles 7 and are connected to an elongate liquid-conducting tube 9 which extends parallel to the centre axis C of the drum.
- the flushing nozzles flush the filter cloth axially from outside, in a direction opposite to the filtering direction, and the flushed-out particles are collected in a discharge trough 10 which is placed in the drum 2 in the upper portion thereof.
- Fig. 6 shows a closing means in the form of a cover 24 for securing the filter segments 13 in the filter support 11.
- the inventive rotary disk filter can suitably be cleaned by means of a cleaning device of the type described in SE-C-515,001 (WO 00/37159).
